The LiveScore app has secured the Irish rights to stream every Champions League match in the competition for the next three seasons.
The score update app, which streamed Serie A action last season, will carry 137 matches each season free to air.
Of those 137 matches, 104 will be streamed exclusively on LiveScore, with 33 other encounters available via other outlets, including on RTÉ, after the national broadcaster extended its coverage of the competition until 2024 last week.
A statement from LiveScore read: "LiveScore has today announced a three-year rights deal within Ireland to live-stream 137 matches each season in the UEFA Champions League fully free-to-air on the LiveScore app."
UEFA's marketing director Guy-Laurent Epstein said: "UEFA is delighted to welcome LiveScore as the new broadcaster of UEFA Champions League rights in the Republic of Ireland. We are excited to see the innovative coverage it will deliver and to bring comprehensive coverage of the best of European club football to Irish fans for free."
